IMPROVEM ENT IN PRESSES.

Specification forming part ofLetters Patent No. 26,855, dated January17, 1860.

To all whom it may concern.'

Be it known that I, THOMAs H. MoCRAY, of Tellico, in the county of Ellisand State of Texas, have invented a new and Improved ranged for pressingcotton and hay, Fig. 2, a

side elevation thereof.

Like letters designate corresponding parts in both figures.

The parts are mounted in an oblong frame, A, at each end of which is abox, B, in which the material is pressed and baled, the cover' and sidesa a thereof being arranged in the usual manner. A cam, E, is rigidlysecured to a vertical spindle, F, in the center of the frame, and drivenby a sweep, G, as usual. The periphery of this cam extends through theentire circle, the eccentricity being uniform from the inner to theouter extremity, more or less, according to the power required to beapplied. The outer extremity, b, also projects around the innerextremity sufficiently far to leave an Open space between it and theinner extremity to admit a key or block, C, as hereinafter set forth.The followers I I, for both bale -boxes, are situated between suitableguides, c o, to retain them in place, and are connected by means of fourparallel bars or timbers, D D D D, the upper pair being separated fromthe lower sufficiently to admit the cam E between them, and the two sidepairs being separated sufficiently to admit the spindle F between them.These bars or timbers are of such length that the followers may actalternately, as will presently be described. In the inner side of thebars D D D D are made sets of vertical notches f f f f, Fig. l,4suiiicient in number for the purpose designed, and the notches ofdifferent bars in each set, respectively, are opposite to each other.These sets of notches are situated apart a distance equal to the throwof the cam E at each revolution. A removable key or block, C, fits intoany one of these sets of notches f f f f, as shown most clearly in Fig.l, for the cam to act against.

The action of the whole arrangement is as follows: The key O is firstinserted in one of the sets of notches f f f f, closeto the innerextremity of the cam, which is then put in motion and forces thefollower forward a distance equal to its throw or eccentricity. Then,just before the outer extremity, b, of the cam escapes from the saidkey, another key or block` (shown in red lines) is inserted in the nextsucceeding notches f f f f, in front of the inner extremity of the cam,which then commences to act on it, and performs another revolution. Thefirst or another key is then inserted in the same manner behind thesecond, and thus the operation is repeated at each revolution of the camtill the bale is suiiiciently pressed. As soon as one bale is pressedand secured, the keys C C are shifted to the other side of the spindleand a bale is pressed in the other bale-box in the same manner, so thatwhile one bale is pressing the empty box is filling. Thus, by the useofthe keys C C, removable to the different sets of notches f f f f insuccession, in connection with the cam E, thereby giving as many turnsto the cam as desired to press a single bale, I am enabled to press thebales with a much less power than would be required to press them if thepressing were completed by a single revolution of the cam, as in othercam-presses.

I do not claim a revolving cam for pressing cotton or other substances;but

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the keys O O, or their equivalents, movable todifferent notches or positions in succession, with a revolving cam,

substantially in the manner and for the purposes herein specified.

In witness that the above is a true specification of my improved hay,cotton, and tobacco press I hereunto set my hand.
